DNS issues

[Sylvain Beucler-2]

Hi,

I'll recap the DNS errors we currently experience:


- ns1.gnu.org refuses requests for dl.sv.gnu.org:

  $ host dl.sv.gnu.org ns1.gnu.org
  Using domain server:
  Name: ns1.gnu.org
  Address: 199.232.41.12#53
  Aliases:
 
  Host dl.sv.gnu.org.formation.cliss21.org not found: 5(REFUSED)


- audio-video neither:

  $ host audio-video.gnu.org ns1.gnu.org
  Using domain server:
  Name: ns1.gnu.org
  Address: 199.232.41.12#53
  Aliases:
 
  Host audio-video.gnu.org.formation.cliss21.org not found: 5(REFUSED)


- ns4.gnu.org lags (last version is oct 16) and thus is interfering
  with our IP changes.


- ns1.gnu.org doesn't replicate changes from savannah-backup.gnu.org
  immediately - it looks like there's something like an hourly refresh
  or something, while the TTL is 300 and the notification is sent
  immediatley, so we'd like to understand how it works.


Cheers,

Hi,

Any progress on this?

I had a "site not found" error again today when going to
audio-video.gnu.org, for instance.

I suppose all these issues are related, so I'm opening one ticket for
each, but feel free to split the ticket if that's more convenient.

1/2 of the DNS servers work, the other 1/2 do not. YMMV.

I've been trying for weeks to get in contact with the person running
ns4. They are non-responsive so far. I tried again today, and have
removed ns4 from our list or nameservers for now. So this should be
resolved now.

Thanks,
Ward.

And the ns4 hostmaster got back to us. They have updated their config,
so I re-added them.

Thanks,
Ward.

These issues are now also resolved. I believe this was the last of the
outstanding DNS issues.

I have just gone over the gnu.org and nongnu.org zone files once more
and made double sure there were no longer any records in there that
belong in your zone files. I found a number of them but I believe they
should mostly have been covered in your zone files already. Anyway; if
something is suddenly missing you can add it to your own zonefiles...
Let us know if you have any further problems.

Thanks,
Ward.
